Improved cake-machine

Lette/rs Patent No. 90,57 7 dated May 25, 1869 IMPROVED CAKE-MACHINE.

The Schedule referred to in these Letters Patent and-making part of the same.

Be it known that I, JOSEPH REPETTI, of Philadelphia, in the county of Philadelphia, and State of Penusylvania, have invented certain new and useful Improvements in Machines for Making Cakes, 85e.; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed draw in gs, making part of this specification, in which- Figure 1 is a perspective view.

Figure 2, a section of the device which operates the plunger.

b Figure 3isa perspective view of the improved dough- Figures 4 and 5 are sectional views of the pins or combs which are used for making annular cakes.

Figure 6 is an elevation of the improved cutter.

This invention relates to the improvement of that class of cake-machines in which the dough is put into a box, having a perforated bottom, the holes in said bottom corresponding to the shape which the cakes ,are intended to assume; and as the dough is forced through these holes by a plungerjust fitting the box, a cutter underneath the bottom detaches the cakes at intervals.

The improvements consist in the combination and arrangement of the devices described.

The motive-power is applied to the pulleys a and a', on the shaft b, a revolving lo`osely on the shaft, and a' being fastened thereto; hence, if the belt o runs on the pulley a', the shaft b is revolved.

The belt o is guided by prongs c c', on the rod d, which latter is bent thus :1, the horizontal portions being supported by the frames e e', and the vertical part ruiming parallel with and behind the back frame e'.

Springs f or f are provided, tending to push the rod always towards the left of fig. l, and thus would move the belt on the loose puller a, were it not for the stopper g, which bears against the arm h, on the rock-shaft t', as soon as the rod is pushed suiciently to the right, to bring the belt o upon the fast or tight pulley, a. Now, as the plunger j, screw k, and finger lreach their lowest points, the finger l depresses the short arm It', on the rock-shaft i, causing the opposite arm, h, to rise and release the stopper g, when the springs for f will push the rod immediately to the left, thereby shifting the belt from the fast pulley a to the loose pulley a, and consequently stopping the machine.

The upright shaft fm, ruiming in bearings fr and lr, is driven by a quarter-turn belt n, running on the driving-pulley p on the shaft b, and the receiving-pulley q on the upright shaft. This shaft carries, underneath the bearing r, a face-plate, s, to which the cutter s is fastened.

Above the pulley pis fastened the eccentric @which gives the usual intermittent motion of the apron n2, by means of the eccentric strap t', levers u and ul, on the upright rock-shaft u, connecting-rod c, pawl-lever v, and pawl 1:2, which latter drives the ratchet-whceI w on the shaft vof the apron-roll w.

lhe descending motion of the plunger is obtained by means of the non-revolving screw k, nut z, fig. 2, ratchet-wheel 1, pawl 2, oscillating arm 3, and adjustable crank 4.

The crank works in the oscillating arm 3, imparting to the pawl 2, which is attached to the arm 3, an alternate circular motion. The pawl will, at its forward stroke, carry the uut z, by means of the ratchet-wheel 1, through an angular distance equal to its own amount of motion. y

The screw k, being fastened into the plunger j, is, like the latter, kept from revolving by the parallel guides 5 5, on the dough-box 10; hence, it follows, that the intermittent revolving motion of the nut, causes in the screw a corresponding rectilinear motion, which in this instance is downwa d.

Whenever the pawl 2 is thrown out of gear with ratchet-wheel l, it being provided for that purpose with a small handle, the plunger may be raised or lowered, at will, by means of bevel-wheels 7 and 8, and handwheel 9. raised to permit the introduction of a new quantity of dough. lhe slide 6, lig. 3, having been broughtpreviouslyunderneath the bottom of the dough-box, the plunger is now depressed by turning the hand-wheel iu the reverse direction until the dough forms a solid mass, then the pawl 2 is thrown into the teeth of the ratchet-wheel l, and the machine started by pushing the knob d on the rod d, in, which" will bring the belt o upon the fast pulley a'.

I do not confine myself to the use of fast and loose pulleys for stopping and starting the machine, for the same object may be obtained by means of plain or fric tion-clutches, which are too well known tc require any descriptions. In that case, the sliding part of the clutch is connected with therod d, the belt running always "in the same plane.

The doughbox, fig. 3, has only three solid or continuous sides, the front side being closed by a hinged door, y, and the bot-tom, y2, being made movable, the latter rests on projections in the interior of' the box, and is provided with V-slides to 'it those ofthe slide 6. The combs x, for forming cakes with holes, are also made movable to facilitate cleaning. They rest in small grooves,and do not project above the surface of the bottom, so that all the material can be pressed out.

The positions of the upright shaft m,and the cutter s on said shaft, are such, relative to the dough-box 10, that, as they revolve, the wire s of the cutter will sweep past the lower surface of the bottom, y2, cutting off all the dough that has been forced through.

The construction of the cutter is shown in iig. 6, where s'Z is a metal frame, 0n which the Wire sl is stretched. The shank `93,-which is fastened to the frame by a small set-screw or other suitable means, supports 1f it is at the bottom of the box, it may be i also one end of the wire. lIt will be evident, that by drawing s3 outward, the wire is stretched to the required tension, the set-screw serving to keep the shank in that position.

The shank ss is provided with a hole, shown by dotted lines, for the purpose of receiving a bolt or'screw', by which'the whole is fastened to the lower side of the face-plate.

There have been'removab'le bottoms used for doughboxes, but they had to be lifted through the box', and my improvement consists in arranging the bottom, so that it can be slid out in front, which is much more convenient. v

The apron n2, with its intermittent motion, the plunger j, counter-shaft b, and fast and loose pulleys, are old devices, and have been used in machinesfor making cakes; nor do I claim as my invention, theidea of puttingpins, combs, or other devices into 'the perforations of the bottom of the -dough-box, when the same arefasteued Awith screws or otherwise; but

What I claim as my invention, anddesire to secure by Letters Patent, isl. The combination of the automatic stopping-device, consisting of the finger l, rock-shaft fi, arms h and h', rod d, spring f', and stopper g, with the plunger j, screw k, and pulleys a and a', or their equivalents, substantially as and for the purpose herein described.

2. The combination of the upright shaft m with the projection fr?, dough-box 10, with its hinged and re'- movable door 7, plunger j, and screw k.

3. The combination of the revolving cutter s with `the dough-box 10, substantially as and for the purpose or combs x, with the dough-box, substantially as i and for the purpose specified.

6. The combination of the bevel-wheels 7 and 8, and handewheel, with the nou-revolving screw k, revolving nut s, and plnngerj, substantially as and for the purpose specified.

7. The combination of the slide 6 with the mova` ble` botttom y2 and dough-box 10, substantially as and for the purpose set forth in this specification.

8. The combination of the cutter, fig. 6, composed ofthe wire s1, frame s, and shank s3, wtha revolving shaft, m, substantially as herein specified.

In testimony whereof, I have signed my name, in presence of two subscribing witnesses, this day of March, 1869.
